A virtual interaction layer. Allows to respond to mouse movement around an element.
npm install --save-dev perimeter
Perimeter is distributed as an ecmascript 2015 module. The sample below assumes you are using browserify and babelify.
import Perimeter from 'perimeter';
// bind to button element
let buttonElement = element.querySelector('.cssSelector');
let buttonPerimeter = new Perimeter(buttonElement, 50);
buttonPerimeter.addEventListener('mouseenter', function(){
// respond when mouse enters the perimeter
});
buttonPerimeter.addEventListener('mouseleave', function(){
// respond when mouse leaves the perimeter
});
buttonPerimeter.addEventListener('mousemove', function(){
// respond to mouse move inside perimeter
});
Alternatively you can use the build version to use a global object (check the recipes)
To create the stand alone version of the library run the following script.
npm run-script build-standalone
This will create a readable version build\perimiter.standalone.js and a minified version build\perimiter.standalone.min.js.
Including this one of these files on a page will expose perimiter under the window.perimiter variable.
Check the recipes folder for sample implementations. ( build the project to run samples )
